<p><strong>Mengatasi Zimbra 2FA Code Did Not Match</strong> &#8211; Beberapa hari yang lalu, saya beserta rekan saya berkunjung ke salah satu klien di daerah Jakarta untuk membahas Fitur pada Zimbra NE. Salah satu fitur yang dibahas saat itu yaitu Zimbra Two Factor Authentication.</p>
<p>Ketika itu klien ingin langsung mengimplementasikan fitur tersebut untuk beberapa akun dahulu untuk ujicoba. Nahh saat ujicoba tersebut, muncul pesan error &#8220;The code you entered did not match&#8221;</p>
<p><a href="https://rizkypratama.id/wp-content/uploads/2018/11/code-did-not-match.png"><img data-attachment-id="808" data-permalink="https://rizkypratama.id/blog/2018/11/07/mengatasi-code-did-not-match-invalid-totp-code-zimbra-two-factor-authentication/code-did-not-match/" data-orig-file="https://i0.wp.com/rizkypratama.id/wp-content/uploads/2018/11/code-did-not-match.png?fit=486%2C282&;ssl=1" data-orig-size="486,282" data-comments-opened="1" data-image-meta="{";aperture";:";0";,";credit";:";";,";camera";:";";,";caption";:";";,";created_timestamp";:";0";,";copyright";:";";,";focal_length";:";0";,";iso";:";0";,";shutter_speed";:";0";,";title";:";";,";orientation";:";0";}" data-image-title="code-did-not-match" data-image-description="" data-image-caption="" data-medium-file="https://i0.wp.com/rizkypratama.id/wp-content/uploads/2018/11/code-did-not-match.png?fit=300%2C174&;ssl=1" data-large-file="https://i0.wp.com/rizkypratama.id/wp-content/uploads/2018/11/code-did-not-match.png?fit=486%2C282&;ssl=1" class="alignnone wp-image-808 size-full" src="https://rizkypratama.id/wp-content/uploads/2018/11/code-did-not-match.png" alt="" width="486" height="282" /></a></p>
<p>Kalau di cek di mailbox.log, ada muncul pesan TOTP Invalid.</p>
<pre>2018-11-07 00:22:02,886 INFO [qtp998351292-150222:http://mail.hostname.id/service/soap/EnableTwoFactorAuthRequest] [name=akun@hostname.id;mid=1;ip=172.16.x.x;port=36708;ua=ZimbraWebClient - GC70 (Mac)/8.8.8_GA_1703;soapId=6497d60e;] SoapEngine - handler exception: authentication failed for [akun@hostname.id], invalid TOTP code</pre>
<p>Setelah ada pesan error tersebut, saya coba ulangi langkah-langkah untuk mengaktifkan fitur 2FA tersebut. Saya coba pelan-pelan untuk memasukkan key yang muncul untuk diinput pada google authenticator, kemudian saya juga pelan-pelan untuk memasukkan Kode OTP yang muncul pada google authenticator tersebut, namun hasilnya nihil, tetap dianggap code did not match/Invalid TOTP.</p>
<p>Saya coba cari referensi dari Wiki Zimbra, error tersebut katanya karena konfigurasi Date pada server tidak sesuai, dan disarankan untuk sinkronisasi saja ke NTP Server. Akhirnya saya coba lakukan hal tersebut.</p>
<p>1. Install paket ntpdate agar otomatis sync ke NTP server ketika server ada proses reboot.</p>
<h3><span style="color: #0000ff;"><strong>Centos</strong></span></h3>
<pre>yum install ntpdate -y</pre>
<h3><span style="color: #0000ff;"><strong>Ubuntu</strong></span></h3>
<pre>apt-get install ntpdate -y</pre>
<p>2. Edit file konfigurasi ntpdate agar menggunakan NTP Server Indonesia.</p>
<h3><strong><span style="color: #0000ff;">Centos</span></strong></h3>
<p>Untuk Centos, edit file berikut ini</p>
<pre>vi /etc/ntp/step-tickers</pre>
<p>Edit file tersebut menjadi seperti berikut ini.</p>
<pre># List of NTP servers used by the ntpdate service. 
 
<span style="color: #ff0000;">0.id.pool.ntp.org 
</span></pre>
<p>Kemudian restart service dan set otomatis up ketika reboot.</p>
<pre>service ntpdate restart 
chkconfig ntpdate on 
</pre>
<h3><strong><span style="color: #0000ff;">Ubuntu</span></strong></h3>
<p>Untuk Ubuntu, edit file berikut ini.</p>
<pre>vi /etc/default/ntpdate</pre>
<p>Cari baris berikut ini dan set agar NTP nya mengarah ke NTP Server Indonesia.</p>
<pre># List of NTP servers to use (Separate multiple servers with spaces.) 
# Not used if NTPDATE_USE_NTP_CONF is yes. 
NTPSERVERS="<span style="color: #ff0000;">0.id.pool.ntp.org</span>" 
</pre>
<p>Jika sudah, save dan jalankan command ntpdate-debian</p>
<pre># <span style="color: #ff0000;">ntpdate-debian</span> 
7 Nov 00:42:37 ntpdate[16263]: adjust time server 202.65.114.202 offset 0.001242 sec 
</pre>
<p>Alamat NTP Server Indonesia yaitu 0.id.pool.ntp.org.</p>
<p>Setelah menjalankan langkah-langkah diatas, konfigurasi date dan time sudah sinkron mengikuti konfigurasi date dan time pada NTP Server Indonesia.</p>
<p>Selanjutnya silakan dilanjut kembali untuk setup Zimbra Two Factor Authenticationnya, dan mestinya saat ini sudah success dan tidak muncul pesan error code did not match.</p>

<p>Mungkin cukup sekian, semoga bermanfaat</p>
